WHEEL.

SPECIFICATION fOrmingf part Of l'aetters Patent No. 603,259, dated May3, 1898. Application filed May 28, 1896. I Serial No. 593,403. (Nomodel.)

To all whom it may concern: 4

Be it known that 1, JAMES E. COMPTON, of

Lynn, in the county of Essex and Commonwealth of Massachusetts, haveinvented certain Improvements in Wheels, of which the following, inconnection'with the accompanying drawings, is a specification.

. My invention is shown inthe present instance as embodied in a wheeldesigned for mechanical usessuch as polishing, grinding, and similarpurposesbut I would not thereby limit the invention,as it is equallyuseful in other classes of wheels.

In the accompanying drawings, Figure 1 is a' plan view, partly insection, on the line a; m of Fig. 2, of a wheel embodying the presentinvention. Fig. 2 is an elevation, partly in section. Fig. 3 is a detailshowing the straining-lever detached; Fig. 4 is a detail showing amodified form of straining-arm, and-Fig. 5 is a detail showing one ofthe weights in position.

The wheel-rim A is composed of any suitable material and may be whole orof one piece, if desired, but, as shown inthe present instance, isformed of separate voussoirs, and the voussoirs are preferably made toconsist of leather material in part and in part of wood, the materialsbeing arranged with alternating sections of each placed side by side inpack, as shown. The sections 4 of wood arepreferably of greaterthickness than the sections 6 of leather. The parts are tapered like thevoussoirs of an arch and may be secured together by cement or otherconvenient and suitable means.

The wheel-hub comprises a disk 8, which is also provided with a flange10, extending inwardly therefrom. Against the disk and flange aresupported a plurality of levers 12. Said levers, something like atriangle in shape, (see Fig. 3,) are supported by one corner against thedisk and flange 10 to permit rocking movement thereon as a fulcrum. Theyare located. about and extend inwardly to ward the hub-center after themanner of radii, the inner ends thereof being at a distance from thedisk .and free of contact with the hub. On the hub is a nut 14, andadjacent thereto is a collar 16 in bearing contact with the free end ofsaid levers. The nut 14 has screw-thread engagement with the hub,

whereby to be moved thereon for carrying the collar forwardly andbackwardly against the levers 12 and rocking the same, as hereinafterdescribed.

In connection with the outer and uppermost corner of the levers 12 areradial arms 18. As shown in Fig. 1, said arms consist of a loop of wire,its loop end being caught over a suitable boss'or hook formation on thelever 12 and the free ends thereof being extended and connected with thevoussoirs of the wheel-rim. To this end the wire ends are provided withlugs or enlargements 20, which, being suitably socketed in the loop orin the material of the wheel-rim, effect a firm connection of the armtherewith.

It will now be understood that movement of nut 14, carrying the collar16 against the free ends'of levers 12 and rocking the levers 12 on theirrespective fulcrum-points, operates to draw the arms for tightening thevoussoirs and thus contracting the wheel-rim. A re- .verse movement ofnut 14 releases the parts by an obverse movement of the arms 18.

Instead of the looped arm and voussoirs, as shown in Fig. 1, an arm maybe employed with a single end connected tothe voussoir or with therimmaterial, as shown in Fig. 4.

Connected with the hub by screws 22 is a disk-plate 24, provided with arib 26. On the rib 26 are weights 28, which are held adj ustably thereonby screws 30, arranged as shown in Fig. 2. Said weights operate as meansfor balancing the wheel in motion and by suitable operation of the screw30 allow of being shifted, as required, to obtain the adjustment forbalancing the wheel, as desired.

I claim 1. In combination, the hub, a series of rocking levers supportedby the hub, a series of arms engaged by one end with the levers, a rimengaged by the opposite ends thereof, and means connecting with the freeends of the levers, to be moved for rocking the levers whereby the armsare drawn together, substantially as described.

2. In'combination, a hub, a series of rocking levers supported by thehub, a series of arms engaged by one end with the levers, a rim engagedto the opposite ends thereof, and means supported adjustably on the hub,in connection with the free ends of the levers,

4:. In combination, a hub, a series of rocking levers supported by thehub, a series of arms engaged by one end to the levers, a rim composedof voussoirs engaged by the opposite ends of said arms, and meansconnecting with the free ends of the levers to be moved for rocking thelevers, whereby the arms are drawn for binding the voussoirstogether,substantially as described.
